ACR39U-UF Smart Card Reader is one of ACS's latest products addressing the evolution of USB standards. This palm-sized reader features a USB Type C connector. The USB Type C Connector features reversible plug orientation and cable direction to fit mobile to device product designs for future smart card applications.

ACR39U-UF uses the same core as the ACR39U Series. It supports ISO 7816 smart cards and various memory cards, as well as microprocessor cards with T=0, T=1 protocols.

Unlike an older USB cable, it doesn’t matter which side is up with a Type-C plug; you can insert it either way. It complies with PC/SC and CCID standards, keeping the device compatible with current applications under USB specifications. ACR39U Smart Card Reader can easily be integrated to a computer-based and mobile device-based environment. Its drivers are compatible with operating systems such as Windows®, Solaris, Linux®, and Mac OS®. In addition, ACR39U-UF may be used on mobile devices running on Android™ versions 3.1 and later.

ACR39U with USB Type C is another breakthrough for ACS readers.
